Specification forming part of Letters Patent No. 37.36%, dated January 6, 1863. i

To aZZ whom it may concern.-

, Be it known that I, LORENZO P. Tnnn, of White Deer Mills, Union county, Pennsylvania, have invented an Improved Shaker-Frame for Thrashing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a shaker-frame having inclined slats and forked rods, arranged and operating substantially as described hereainfter, so as to insure a thorough agitation of the grain and a complete separation of the straw from the kernels and chaff.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure l is a sectional elevation of my improved shaker-frame for thrashingmachines; Fig. 2 a plan view, and Fig. 3 a side view.

Similar letters refer to similar parts throughout the several views.

The shaker-frame consists of the two side pieces D D, connected together by the inclined slats E E, and at thefront of the frame by the inclined plate or board F. The upright posts A and A and longitudinal beams B B are supposed to represent a portion of the frame of the thrashing-machine, to which the shaker is suspended in the following manner: Two rods, a and a,pass through suitable staples secured to the under side of the shakerframe, the rod to being situated near the front and the red at near the rear end of the said frame. Both rods are turned up at the ends, the turnedup end of the rod a being hung to the longitudinal beams B, and the turned-up ends of the rod a fitting in recesses formed in the uprights A A. Motion is communicated to the shaker'frame from the crankshaft (2, through the medium of a connecting rod, 1), the said crank-shaft being driven from any rotating shaft of the thrashing'machine. The shaker-frame is so hung to that of the thrashing-machine that the former during its movements will assume the two positions indicated by the plain and dotted lines, Fig. 3,

the dotted lines representing the position of the shaker-frame when it has reached the limit of its backward movement, while the plain lines indicate the position of the frame when it has reached the limit of its forward movement-in other words, the frame has a vertical and horizontal movement combined.

It will be observed that the slats E E are inclined on the top, and that an open space intervenes between them, through which space the grain and chaff, when separated from the straw, can pass to the usual sieves. A series of small wires, 6, project from the rear end of each slat across the aforesaid spaces, and from the rear end of each slat also project a series of rods, cl, forked at the end and inclined to an angle of about thirty degrees, similar rods, also forked at the end, projecting from the rear of a board, f, secured to the inclined plate or board F.

Operation: The combined horizontal and vertical motion being communicated to the shaker-frame, the stalks of the grain, with the husk of the kernels disintegrated by the combined action of the usual spiked cylinder and concave of the thrashing-machine, will be deposited in the first instance on the inclined board F at the rear of the shaker.

From this point the stalks are carried forward by the peculiar motion of the shaker until they are discharged at the rear of the frame, the grain and the chaff having in the mean time passed through the spaces between the slats, the wires 0 being a sufficient distance apart from each other to allow for this passage of the grain and chaff, and yet sufficiently near each other to prevent the escape of straw to the sieves. The object of the forked rods (1 is to seize the stalks and to maintain them in a position above the slats, thereby preventing the clogging up of the spaces between the same. The forked rods also assist to impart the desired thorough agitation to the stalks. It will be observed that there are two recesses, It and h, in each of the posts A, the upper recesses enabling me to raise the rear end of the shaker when it is desirable to allow the stalks to remain a longer time on the said shaker than they would if the latter occupied the horizontal position shown in the drawings. When cloverseed has to be thrashed, a few of the forked rods 61 are arranged at an angle of about fifty degrees, as

shown in the drawings, so that the clover straw can pass round these rods and not over them.

I claim as my invention and desire to secure by Letters Patent A shaker-frame having inclined slats E and forked rods d d, arranged and operating substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LORENZO P. TEED.
